>< Tl;dr: A species known as the Ecumene are mention in both halo and destiny, that are drescribed in a vaguely similar fashion. They were wiped out by similar species, the hive and the flood. I believe that destiny is far in the future from halo, after mankind has somewhat faded out, because of a lot undeniable conenctions/coincidences, whatever you choose to believe.
>< No hate here please, if you think im wrong you dont need to be a bïtch about it :)
>< So i was watching a lore video by Halo Follower discussing different enemy forces when i heard a familiar name memtion, the Ecumene. In halo, this is the formal name for the forunners, a highely advanced space-faring species whos capabilities were far superior to all other species, till they were nearly wiped out by a precursors. I recognized this name from the book of sorrows, but couldn't quite remember who they were, so naturally I googled. As stated by Destinypedia, the Ecumene were a highly advanced interstellar government, but they were destroyed by Oryx's armies. In halo, they were killed by the flood(the forerunners were created by the precursors, which turned into the flood, and the forerunners were mainly wiped out by the last remaining precursor. So they were indirectly killed by the flood, in a way), which are very similar to the hive. Coincidence? I think not. Forerunners in halo supposedly could do crazy shìt like create suns, and blackholes, and even the Halo rings. Their crazy abilities could be the reason they are described as a government in destiny, because they create the laws of nature. All of this makes me believe that destiny may be far in the future after halo. Other connenctions lay in the similarities in races in destiny, such as promethians vs l. the vex, covenent vs. the fallen, cabal vs. the brutes, and hive vs. the flood, and as I've said, the ecumene that are mention in both games. I think destiny is set in a period of time far after halo took place, which is described as "the golden age." One last though I've had is that the vanguard could be a simplified, poor mans UNSC. Anyone else have thoughts about this?
